INTRODUCTION:
The FRC’s 2025 report shows a profession still growing but with pressure points: slower membership growth, a flat or slightly declining student pipeline, ongoing audit-market consolidation and inspection findings of variable quality beyond Tier-1 firms. For businesses, this means tighter auditor capacity, rising skill demands (data/AI), and a need to strengthen finance operating models now.
What is the FRC’s Key Facts & Trends report and why is it influential?
The Financial Reporting Council’s annual Key Facts & Trends in the Accountancy Profession (KFAT) provides a statistical snapshot of UK and global accountancy bodies and the Public Interest Entity (PIE) audit market. It’s widely cited because it aggregates hard numbers on membership, students, training capacity, and the composition of PIE audit firms, the market that audits listed companies, banks, and insurers. The 2025 edition (the 23rd) was published on 15 October 2025.
What it covers in 2025 (at a glance):
- Members and students across eight professional bodies (ACCA, CAI, CIMA, CIPFA, ICAS, ICAEW, AIA, AAT).
- PIE audit firms’ revenue mix and participation.
- Diversity data (selected protected characteristics) and training capacity.
- A companion spreadsheet with the underlying data tables.
What headline numbers changed in 2025, and what do they signal?
How is overall membership shifting?
- Members (UK & ROI): over 408,000, up 0.8% between 2023 and 2024.
- Members (Worldwide): over 623,000, up 1.1% over the same period.
- Audit Qualification awards: approximately 1,800 in 2024 (down from 1,900 in 2023).
- Approved training offices (UK & ROI): around 9,600, with about 60% under ICAEW.
What it means: The profession is still expanding, but more gradually. The supply of newly qualified statutory auditors is softening, which can constrain auditor capacity over time.
What’s happening to the student pipeline?
- Students (UK & ROI): under 155,000, down 0.3% between 2023 and 2024.
- Students (Worldwide): under 585,000, down 0.1% overall, though the five Recognised Qualifying Bodies (RQBs) saw UK/ROI students rise from roughly 113,000 to 116,000 (notably ACCA growth).
- AAT: Membership in the UK and ROI decreased by nearly 2%, but student numbers in the UK and ROI increased by over 30%.
What it means: Pipeline signals are mixed, overall flat-to-down, with bright spots (ACCA, AAT students). Employers should plan for scarcity in mid-level talent and invest in training for data and assurance skills.
Are fewer firms serving the PIE audit market?
The report notes an ongoing trend of consolidation, with a decrease in the number of registered statutory audit firms, the total fell to 3,760 in 2024 from 4,038 in 2023.
Participation: 31 PIE audit firms (of 34 contacted) took part in 2025 vs. 33 of 41 last year, a higher response rate (91% vs. 80%) alongside fewer firms contacted, reflecting exits and consolidation dynamics.
What it means: Concentration remains a structural feature of UK PIE audit. Businesses even mid-market can feel capacity constraints, especially during tender cycles or in specialised sectors.
Has audit quality improved and where are the gaps?
The FRC’s July 2025 inspection cycle reported continued improvements among Tier-1 firms. Five of the six Tier-1 firms achieved positive outcomes on at least 90% of audits inspected in 2024 a material improvement compared with earlier inspection cycles. However, quality remains uneven beyond Tier-1, and specific mid-tier firms were urged to accelerate remediation.
Why this matters to you:
- If you’re a PIE or on the FTSE indices, you’ll likely experience stable quality and established methodologies from Tier-1 firms but with premium pricing and tight schedules.
- If you’re mid-market, challenger firms may be attractive on service model and sector fit, but diligence is essential: inspect partner capacity, file review culture, and how the firm is addressing recent AQR findings.
What did the FRC say about SME audits in 2025?
In July 2025, the FRC released emerging findings from its SME audit-market study and consulted on a practice note to promote proportionate audits for smaller and/or less complex entities. According to the report, the SME audit market encompasses around 2,000 firms and over 70,000 audits annually, with an estimated fee pool in the region of £1.5 billion. Challenges include standard scalability, perceived regulatory burden, and uneven tech adoption among smaller practices.
What it means: Many SMEs can access audit services today, but frictional costs and process inefficiencies remain. Expect updated guidance, more consistent RSB supervision, and FRC-led initiatives on SME-friendly technology. Plan for earlier year-end readiness and clear evidence trails to keep audits proportionate.
Where do these trends hit your finance team first?
Will talent tightness affect delivery cycles and controls?
Yes. Slower membership growth, a flat student base, and an only modest flow of new audit qualifications imply talent bottlenecks in financial reporting, technical accounting, and audit readiness.
Warning signs to watch:
- Month-end close creeping from T+5 to T+10 (or longer).
- Repeat audit queries on estimates/impairment and revenue recognition.
- Overreliance on one or two key staff for consolidation or IFRS/FRS 102 judgements.
- Under-investment in data quality and workflow automation.
How does audit-market concentration change your options?
The FRC’s December 2024 update reported that non-Big Four firms held approximately 13% of FTSE-350 audit engagements in 2023, while the total audit-fee pool for UK PIEs was around £1.4 billion. For many companies, this translates to fewer viable choices, fee pressure, and switching costs.
What should you be doing now to future-proof your finance and audit functions?
How do you select (and manage) the right auditor in a tight market?
Audit-client readiness checklist:
- Capacity & coverage: Ask for engagement-team FTE plans, partner-to-manager leverage, and back-up resourcing.
- Quality track record: Review the firm’s AQR results and specific root-cause analysis themes addressed.
- Scope clarity: Define material risk areas early (e.g., impairment, going concern, revenue cut-off) and align PBC lists to avoid scope creep.
- Independence & non-audit services: Confirm prohibited services, fee ratios, and escalation routes.
- Data & controls: Evidence ITGCs, reconcile key sub-ledgers, and document management-review controls.
- Contingency: Maintain a tender file and plan B in case of timing or independence conflicts.
How should your finance team’s skills matrix evolve?
From compliance → insight → assurance enablement.
- Technical: IFRS/FRS 102 updates; impairment, revenue, ECL models.
- Digital: Data-engineering basics (chart-of-accounts governance, ETL hygiene), BI tooling, and audit-ready data extracts.
- Controls: Formal management-review controls, system-access governance, and evidence capture.
- ESG/Sustainability: Narrative controls, data lineage, and readiness for assurance on non-financial metrics.
Action ideas:
- Introduce data stewards within finance.
- Pilot AI-assisted reconciliations and anomaly detection in non-critical cycles first.
- Rotate seniors through Financial Reporting → FP&A → Controls to build well-rounded bench strength.
- Use KPIs blending timeliness (close lag), quality (post-close adjustments), and efficiency (PBC first-pass acceptance rate).
What could go wrong if you wait?
- Small-firm blind spot: SMEs often defer process upgrades until a disruptive audit season forces the issue. The FRC’s SME audit-market study explicitly targets proportionate auditing, but your evidence trail must still be robust.
- Switching costs: In a concentrated market, changing auditors can take 9–12 months from market-sounding to handover. Build audit-file portability with clear workpapers and reconciled sub-ledgers.
- Quality exposure outside Tier-1: Inspection data show improvement at the top tier, but variability persists across the market. If you choose a challenger, scrutinise their remediation plan and coaching culture.
Conclusion The 2025 FRC message is clear: the profession is resilient, but you can’t run 2026 on 2019 processes
KFAT 2025 portrays a stable yet capacity-constrained profession. Membership growth is modest; student numbers are mixed; the number of PIE firms is down even as response rates improved; and quality, while strong at Tier-1, is not uniformly distributed.
At the same time, the FRC is lowering friction for SMEs through proportionate audit guidance, and inspection timeliness and transparency are improving good news for the broader market. The businesses best-positioned for 2026 are already standardising data, tightening controls, upskilling their finance teams and designing audit-ready processes.
